Outside Front Cover: Boosting Current Density of Electrocatalytic CO2 Reduction using Metal-Enzyme Hybrid Cathodes (Angew. Chem. Int. Ed. 30/2025)

Graphical Abstract
A hybrid metal–enzyme electrode integrating bovine carbonic anhydrase (bCA) with a metallic catalyst facilitates enhanced CO2 electroreduction. The bCA dynamically catalyzes the reversible conversion between CO2 and bicarbonate, enabling local CO2 regeneration at the catalyst surface. This enzyme-mediated CO2 supply significantly boosts CO2RR current density beyond mass transfer limits, even under flooding conditions, as reported by Jinwoo Lee, Jungbae Kim, Ki Tae Park et al. in their Research Article (e202504380).
